The MegaMoto Dual Channel H-Bridge Motor Controller for Arduino 13A, 5-28V is a versatile and robust motor control shield designed for use with Arduino-compatible base units. It allows users to manage high-current, high-power motors efficiently, making it ideal for applications in robotics, scooters, industrial controls, and more. The MegaMoto can handle up to 30A of current at voltages up to 28V, providing over 800W of power. This capability enables Arduino users to control powerful motors without the need for complex and unreliable connections.
The MegaMoto features a dual half-bridge circuit configuration, which can be set up as a full H-bridge for controlling a single motor with variable speed in both forward and reverse directions. Alternatively, it can control two independent motors in a uni-directional manner. The flexibility of the MegaMoto is further enhanced by its ability to stack multiple units on a single Arduino base, allowing for the control of multiple motors simultaneously. This is achieved through the use of jumpers to select the appropriate Arduino signals for the Enable and PWM inputs.
In addition to motor control, the MegaMoto can manage other DC loads such as lights, solenoids, relays, and valves, provided they fall within the specified voltage and current range. This makes it a highly adaptable component for various electronic projects and applications.

Stacked two of these on the Arduino to drive two Treadmill motors (each rated for 130VDC and 18A). The motors are mounted beneath a piece of plywood and along with a front caster we have created a nice little Arduino controlled 2WD cart. My students are learning how to program this "RoboCart". Using two UPS batteries (12V DC for each motor) we are able to drive the cart around. We are using one shield per motor so we can forward or reverse the motors to drive the cart forward, backward, and do circles. We have not started testing with braking code yet but the H bridges have yet to get warm during our routine testing and at only 12V DC we got more than enough speed out of the motors without pushing the shield too hard. The real test will come when we brake the cart to a stop rather than coast. The downloaded documents are excellent and made connecting and using these shields very easy.

As advertised
Appears to work as advertised! Have not had an opportunity to run with it under load yet? And even then it will only see about 60W tops. they're always pushing you to review products before you have an opportunity to run them through their paces...

Robust and Easy to Use
Robust, reliable and easy use shield. Comes with a user manual which is very helpful. The speed and direction of each shield is easily controlled by two digital pins of the arduino board.
